Another weapon of similar form is ruddled and longitudinally grooved, and at one 
end is cross-hatched. 
An interesting form of this type is represented by several examples made from 
a dark wood, in which the ends terminate in a central mucro, with emarginations on 
each side. One face, probably the obverse, is highly ornate and slightly convex ; 
the reverse being flat and longitudinally grooved. The carving in one case consists 
of a median line of elongately-oval figures, interrupted at the centre of the weapon 
by a broad transverse bar, with a narrower bar at each end. The convex and concave 
edges bear a festoon pattern, the festoons longitudinally grooved, and not necessarily 
facing one another on opposite sides. The synclines of the festoon outline are each 
distinguished by two transverse notches or nicks (Pl. xxxu. fig. 1). These weapons 
have a general measurement of two feet and half an inch long, two inches wide, and 
weigh ten ounces. 
Another single weapon is similar to the last in every respect except the 
sculpture. The median line of oval figures is replaced by two such, dividing the 
surface into three parts, a broad central band and two lateral zones. The latter 
exhibit alternate V-shaped and irregular half-circles on one half the boomerang, 
replaced by semi-ovals on the other, all cross-hatched (Pl. xxxu. fig. 2). There is, 
however, no transverse central band. Length, two feet ‘one and a-half inches ; 
breadth, two and a-quarter inches ; and weight, ten ounces. 
A third form is identical with the last, only in this case a median transverse 
band oceurs (PI. xxxm. fig. 3). The side sculpture consists of half-diamond figures, 
with two V-shaped marks on each re-entering angle. 
In the fourth and last boomerang of this type, the central surface is occupied by 
a four-line band returned again and again upon itself, forming a series of loops. The 
margins bear alternate large and small cross-hatched squares. The weight of this 
weapon is eleven ounces. 
A rather similarly sculptured boomerang to Pl. xxxu. figs. 1-3 is figured by 
Lumholtz* from Central Queensland, in so far that the weapon is medianly and 
transversely divided by an incised bar, one half the surface bearing two rows of 
consecutive ovals, and the other half three. The margins are sculptured with 
triangular festoons as before, but the ends of the weapon are not mucronate. 
These highly ornamented boomerangs seem to be eminently typical of North 
Australia, and so differing from those of the southern part, a fact which has not
